They keep banging on about this and I need good arguments why they can't have a dog.
I had a dog when I was a kid. They are a lot of work. A 5yo and an 8yo will not be able to take the dog for a walk on their own (I used to when I was 7, but I don't think this is allowed any more), so this means it will be me, getting up early to do this before work and doing it in the evenings. I have no time to myself as it is and this will take up even more of it.
So what convinces small children dogs are a bad idea?
